I had a look at
http://www.skyatnightmagazine.com/fe...-mounts-part-1 and the OTA on mine might not be balanced correctly. my brother in law bought the scope 2nd hand and the tube rings screws are so tight or stuck I can't undo them.
the Dec slow motions are the worst and that could be because of the lob sided ness of where the OTA is. I might need new rings and an angle grinder
